Note: Temperature stabilities listed on the website are for the best possible stability in that series. Next to
quantity, Frequency vs. Temperature is the highest cost multiplier. Please do not over specify temperature
stability as we will 100% test units to your requirements. The temperature ranges listed above are industry
standards. However, if for example your requirements were for -33 to +55˚C please let us know, by choosing
-40 to +85˚C arbitrarily you will be paying more than is required. Custom stabilities are always welcome and
recommended. We do not charge extra for custom temperature ranges or stabilities.
